Yes.  Have a look at the new boost::python::import() function - I use it to 
import dependency modules, too.  Or, if you are using an older boost version:

BOOST_PYTHON_MODULE_INIT(bar)
{
    // import foo to make sure that basic converters  are available for
    // default arguments:
    {
        PyObject *fooMod = PyImport_ImportModule("foo");
        Py_XDECREF(fooMod);
    }
    ...
}
